*sidenote: theres alot more im probably forgetting and im doin this on my lunch break, so i don't have alota time at the moment, sorry. but If ya'all need anymore information just lemme know.

I've had a few stock ka-t's i can try to remember the specs on them too if wanted.
might have a dyno graph or two on those ka's.



graph.

Fuel?

[ka-t240sx]

oops, my bad. 94 octane pump

[beercandrifter]

some awesome numbers for 10psi

man i wish i would have dynod my car at 25psi on that setup, would have probably just slapped in new pistons lol.

looking good man

[jholman05]

Nice very impressive for such low boost!

[supakat]

Did you degree the cams?

[ka-t240sx]

Did you degree the cams?

No, not really, just shimmed them properly, I still have the stock cam gears.
Should probably invest in some JWT gears haha.

I haven't had the time/money to get back on the dyno yet.

I wouldn't mind going for 16-18 psi on pump for next year but im more than happy with where im at right now.

[sdaigle240]

wow thats the stock housing? that spools sooner than i thought it would. very nice.

[Mercury_Hg]

Are you running a BOV? I anticipate having a setup very similar to this one in the near future.

Arias 8.8:1 Pistons
Eagle Rods
Rebuilt head
JWT S1 Cams
HX35
JGS400 wastegate 7-8psi
3" dp w/ 2.5 dual exhaust
White bunny clutch setup
Nistune Type 3 board
740cc injectors

[airman]

Cool. I somehow missed this dyno sheet. Very similar to my old setup. CP, Eagle, HX35, 10-15psi, yadda yadda. At 10psi this is about what I was seeing in virtual dyno, so cool. Your cams help out though, stock S13s for me.

And oh, seeing your dyno curve reminds me that I miss my HX / turbo in general 300ft-lb at 4k RPM? Yes please!

[KA-T S12]

What manifold is that?

I noticed a huge difference in switching from stock cams to the 272's. Some day soon i plan on degreeing them properly. I have a feeling there is some more power to be made with them degree'd properly.

I love my holset. Wouldn't trade it for anything else and 300 ft-lb @ 4k is pretty awesome. Just wish it didn't drop so much from 6k to redline.

[sr20drag]

bullseyepower T3 .70ar turbine housing will give you 300rpm's of spool and lose nothing up top. Well worth the $200 they go for on extremepsi. I made 411whp with one at 20psi on a sr20 on 93oct and a jwt rom tune years ago. It will like 16-18psi a LOT better. Jst starting to get into the effeciency range of that turbo at 18psi. They really love E85 and 40psi.....

[supakat]

I bet those head studs are helping out a lot. I was making around 320whp on 10psi but lifted the head. Great power and I love the HX. Great turbo.

[jaysol92]

nice numbers for 10 psi ! arp head studs ftw

[supakat]

nice numbers for 10 psi ! arp head studs ftw

He has 11mm not the 10mm. I have 10mm but still managed to lift the head. I think it first started when I was at 15psi tuning and ran a 600cc bike. LOL.

damn! running with bikes and lifting heads with arps, how much you putting down??

He ran 700 whp with 10mm arp head studs. I think miami240 said its all in the tune.

[supakat]

Yea, it is all in the tune. I leaned out to 13.5 afr's I think and my timing was advanced quite a bit. I however got a new timing map. Runs great even for 13psi. ARP's and cosworth has been holding up. 400whp will run with 600cc bikes. you need like 700whp to run with 1000cc.

[Berserker]

Yeah I had same issue when I leaned out. I threw in new felpro headgasket with 10mm arp headbolts resurfaced head and ran that motor 21 psi 400whp on 50 trim(e85 stock block) for a while before I build this current motor. Sold that motor with excelent compression.

I would LOVE to run E85 but there is absolutely no stations up here that sell it.
94 octane is the best i can get
I'm hoping to toss her back on the dyno in a couple months and run 17-20 psi. There's still a few small issues i need to sort out before i bump up the boost.

I'm thinking about switching to the full race twin scroll manifold. I'm tired of constantly cracking this current manifold. And possibly the excessive intake but i don't really want to loose my mid-range for a little top end gain.

400 on stock internals is nice , I'm shooting for that range on 93 pump with meth on a 50 trim also.

[ka-t240sx]

Heres a vid, Rear tyres were 245/45/17 Falken Azenis rt-615k with ~25psi. She feels kinda slow :/ maybe im just used to 10psi lol. Don't plan on upping the boost until i get a better exhaust manifold/twin scroll.

[neverlift]

0 mph ftw lol

[toky042]

damn pulls hard

[ka-t240sx]

0 mph ftw lol

LOl yeah, speed sensor is friggard.

damn pulls hard

Yeah, not bad for only ~10 psi. Startin to feel slow though. Probably just getting used to it that's all.

[toky042]

hoping to get the same turbo, seems pretty good eh

[Grant]

good number man, gotta love the holset turbo and bc cams.
